Title: Improvements in or relating to flexible mountings for engines
IPC: B60K5/12
Filed: 1932-09-24
Abstract: 407,974. Mounting engines. NAPIER & SON, Ltd., D., 211, Acton Vale, Acton, and SEWELL, C. W., 2, Holly Park Road, Finchley, both in London. Sept. 24, 1932, No. 26566. [Class 122 (iii).] To minimize the transmission of vibrations to a motor vehicle or other frame, an internal-combustion or other engine is supported by one or more pairs of pivoted links so arranged that lines drawn through the pivotal centres of each link of a pair intersect on the longitudinal axis of gyration of the engine. The engine may be supported in such manner at one end only, the other end being supported by a single resilient or resiliently mounted member located about the axis of gyration. Preferably, springs or rubber blocks are provided to limit the amplitude of oscillation, such connections also serving, if desired, to support the engine at or near one end either in addition to or instead of other supporting means. Frictional or other damping devices may be associated with the pivotal connections of the links or the bearing bushes of the pivotal connections may be of rubber or other flexible material. The engine and gearbox unit A, having an inclined longitudinal axis of gyration X, is supported towards the front end by a pair of links C each pivoted at one end to a bracket A<2> on the engine and, at the other end, to a bracket B<1> on a chassis longitudinal B, the arrangement being such that, in the position of rest, lines Y, Y<1> through the centres of the pivots of each link intersect at X<1> on the axis of gyration. The brackets A<2>, B<1> are of U- shaped cross-section, one fitting within the other, the clearance required for oscillation being small. In a modified arrangement, the frame brackets are below the engine brackets, the links C being in compression instead of tension. The rear end of the engine unit may be supported by a single rubber buffer D<1> on a cross frame member D<3>, Fig. 1, or by a U- shaped frame member G, Fig. 5, bearing on rubber buffers G<2> bolted to the longitudinals B, providing in either case for oscillation about the axis of gyration X. In a third form, Fig. 7, the rear mounting comprises links H<2>, the lines Y, Y<1> through which intersect at X<1> on the axis of gyration. At the sides of the unit, buffers E, Fig. 1, are arranged between brackets El, E<2> on the engine and frame respectively to limit the amplitude of oscillation or these buffers may also support the weight at the rear end, the line joining the centres of the buffers passing through the axis of gyration. Reference has been directed by the Comptroller to Specification 393,339.

IPC: G05F1/585
Filed: 1967-06-13
Abstract: 1,179,449. Automatic voltage control. MULLARD Ltd. June 13, 1967, No.27152/67. Heading G3R. A power supply arrangement comprises two regulated supplies having one output terminal of each commoned at B and providing outputs of opposite polarity at terminals A and C, at least one of the regulated supplies being rendered operative at switch on by a voltage applied through a diode D9 from its associated unregulated supply, and the diode D9 being rendered non-conducting during the normal operation of the arrangement by a voltage applied thereto from the other of said supplies. As shown, the unregulated supplies are constituted by bridge rectifiers D1-D4 and D5-D8 which are connected to respective secondary windings of a transformer T. The respective regulating elements are series transistors VT1, VT2 and VT3, VT4 connected as Darlington pairs, with associated control transistors VT5, VT6. In the absence of diode D9 transistors VT2 and VT3 would not conduct at switch on and no output would appear at terminals A and C; the diode D9, however, allows the voltage at rectifier D5-D8 to be applied to the base of transistor VT4 whereby transistor VT3 is reduced conductive, and the voltage then available at terminal C is applied over resistor R10 to the base of transistor VT1. Thus, transistor VT2 is also rendered conductive so that an output voltage is them available at terminal A; this latter voltage is applied to diode D9 over a resistor R9 to render the diode non-conductive, and the regulating elements then operate in conventional manner to maintain constant the output voltages between terminals A, B and B, C. A second diode may be provided so that both regulated supplies are rendered operative at switch on, and such a modification is described with reference to Fig. 2 (not shown).
Patent GB-1554904-A (GB)
Title: Motor control circuit
IPC: H02P1/44
Filed: 1976-06-30
Abstract: Both the main winding (11) and the starting winding (10) of a single-phase induction motor can be connected via a pneumatically operated rotary switch (12) to the terminals (14, 20) of an AC voltage source. The rotary switch (12) has six stationary contacts (1-6) and a rotating element with eight contacts which are connected to one another in the manner shown. Whenever the rotating element of the switch (12) is operated, said rotating element is rotated through 90 DEG . When the rotating element is in the position shown, the motor runs in the one rotation direction. In order to start the motor again once it has been stopped, the rotating element of the switch (12) is rotated through 90 DEG  with respect to the position shown, as a result of which a connection is produced via the rotating element between the stationary contacts 1 and 4, 2 and 6, and 3 and 5. The interchanging of the connection of the starting winding (10) which is produced in this way results in the rotation direction of the motor reversing. The motor is preferably used for driving a refuse-disposal device. <IMAGE>
